Bought a bunch of "Premium" 8' 2x4's to build a small storage shed next to my shop. I cut the last piece to attach to the ends of the rafters and I swear to God it was possessed! No problem cutting it at all but when I went to nail it, I bent 3 16d nails trying to get through the damned thing. I couldn't get the bent ones out with my framing hammer so I cut them off with a sawz-all. I ended up drilling holes so I could drive the freaking things through and into the ends of the rafters. I was about to take it to the church up the block and have it exorcized!
